Summary:A switch-on, switch-off arrangement for electrical load circuits includes a contactor with a magnetic drive, consisting of a magnet yoke with a magnet coil and a magnet armature, to which are coupled bridge contacts as movable contactor-contacts, via a contact retainer. A device for protection against the contacts welding together is provided. The anti-contact-welding protection comprises devices for rapid switch-off of the contactor-magnetic drive (10), with which the bridge-contacts (5a,5b) remain permanently open as the main contactor contacts.
